wireless aerials and like structures, and` which is very simple. and durable in construction and arranged to permit of tiring the projectile from a gun the same as an ordinary projectile and without dangerof injuring the bore of the gun.

In order to produce the desired result, useis made of raking members pivoted on the body of the projectile and adapted to slide in the direction of the axis of the projee 'tile while in folded osition, and retaining means to hold the ra ting members in fold ed forward position and to allow the raking members to slide rearwardly into released position owing to the inertia thereof on the firing of the projectile so that the raking fingers are subsequently swung upward and rearward into open position. Use is also made of abutments on the projectile to limit the rearward swinging motion of the raking members 'with a view to hold the latter in an acute angle position relatively to the axis of the projectile.

A practical embodiment of the invention is represented in the accompanying drawings forming part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the projectile; Fig. 2 is a longitudinal central section of the samel on the line 2f-2 of Fi. 1; Figs. 3

and 4 are sectional side elevations of the rear end of the projectile and showing the successive steps for placing a raking member in position on the body of the projectile; Fig. is a sectional side elevation of 'f shown the raking member in exion after the projectileis t-t of ilig. 1 and showing more particu-- f the projectile on the line.

larly the filling block in position after the raking member is inserted; Fig. 7 is a plan view of a portion of the projectile with one of the raking arms in rearward released position; Fig. 8 is a cross section of the pro' jcctile on the line 8-8 of Fig. 1; Fig. 9 is a similar view of the same on the line 9-9 of Fie. 1; andl Fig. 10 is a similar view of the same on the line 'l0-l0 of Fig. 1.

The body of the projectile is of the usual shape and is provided on its peripheral face with a` series of longitudinally extending recesses 16 in each of which is held a raking member 17 extending therefrom beyond the Ipoint of the body 15 and adapted to swing outward and rearward into an acute angle position7 as indicated in Fig. 5. Each of the raking members 17 is provided at its rear end with an open eye 18 adapted to 'engage a transverse pivot 19 attached to or forming part of the body 15 and extending into the enlarged rear portion 20 oi? the corresponding recess 16. Each raking member 17 is preferably in the form of a bar of triangular shape in cross section to provide a cutting edge 21 at its bottom and each bar terminates at its outer end in a hook rlhe raking member 17 when in folded position extends within the peripheral face of the body 15 and consequently of the bore of the gun from which the projectile is fired.

rllhe enlarged portion .20 of the recess 16 and the 'eye 18 of a. raking member 17 are so constructed that each rakin `member is mounted to slide lengthwise, t at is, from a normal. forward position as shown in Figs. 1 and 2 to a rearmost position as illustrated in Fig. 7. "When the raking member 17 is in a forward position it is held clamped in thisposi-tion to prevent accidental opening i of a. raking member and for this purpose each side of a raking mem-ber 17 is provided with rais/ed clamping portions 25 clampingly engaging the corresponding portions 26 formed on the side walls of the recesses 16 (see Figs. 1, 2 and 7). When the projectile is fired 'the percussion action in-` feuses the ral-linge member 17 lil@ f the recesses 16, the said rear walls beingk ent forward at the upperportions to proide an overhang, as will be readily unerstood by reference to Figs. 1, 2, 4 and 5.

In practice the enlarged portion of proj ect1le,.whereby to'allow the raking memich recess 16 is extended to one side of its ecess to permit of conveniently hooking the ve 18on the pivot19 and then moving-the ve 18 transversely along the pivot 19 .until 1e raking member 17 is in register .with the nrresponding recess 16 to allow ofswing.

1g the raking member into folded position. Lfter the raking member is imposition a lling block is placed in the extension of .ie enlarged portion 20' to prevent acciental return movement of the eye 18 on-the ivot v19* at the time the corresponding rakig member is in open position. The' filling lock 40 is preferably fastened in place by screw 41 and the filling block is provided Yith a slot 42 extending from the bottom pward vto straddle thepivot 19, as will be' eadly understood by reference'to Fig. 6.

From the foregoing it will be seen that hen the projectile is fired from the gun ae raking members 17 swing into anacute ngled .position relative to the axis of the ody 15 so lthat the cutting edges 21 ofthe aking members readily cut through wire ntanglements, vshells of balloons and the ke, and the hooks 22 readily hook'onto the urrounding parts ofthe structures to carry he4 same along and to tear such structures sunder.

-The raking members 1i' shown and de` :'ribed are very simple and durable in contru'ction and are especially serviceable for se ori-projectiles up to,-.say, six inchesin ia'meter.

yThe*projectile-is veryserviceable for use a 'gun'smounted `on aeroplanes and other 1 erial vessels ,for vfighting enemies aerialraft.VH
